X11 with i3, the setup I’ve used for years, is not bug ridden. There are quirks, but nothing fundamental, nothing that makes it a bad user experience.
Wayland, on the other hand, has been a dreadful experience. Some of the most fundamental things, like cursor rendering, window rendering, multiple monitors, clipboard, all have problems doing the basics.
To be clear, this is what I actually expected. My disappointment is that people have been preaching about Wayland for years, pushing a stronger and stronger line that it is fantastic, has great support, and is ready to switch to now. That just isn’t the case.
